I get 58-63 mpg even when riding like a Hooligan! I am at a higher altitude, so that helps... Still pleasantly surprised though!

How many tanks have gone through to establish this 58-63mpg estimate?

I am at 55.7mpg avg. through 72 fill ups. My best was 59.5 and I am -3 in the back. Even at altitude 58mpg is not happening while riding like a "Hooligan" unless hooligan means something different to you. Under ideal conditions for the whole tank I could see 63mpg happening but you have to be riding with the intent on getting good mpg or just get stuck with a killer tail wind for a long period with little decel/accel.

I have seen 58mpg on a tank when I was mainly rolling downhill at low and constant speed. The best I have ever seen on the Tiger was 61mpg and that was literally rolling downhill at constant speed with a tail wind from Carson City to Mono Lake and I filled up with just 89 miles on the clock - so there is room for error.

I can't believe the 58 to 63 being accurate. I can even hardly believe your 55mpg average if that is US gallons.

Well, I am filling from a pump in the US so I assume they are selling by the US gallon. I've checked my odometer vs. GPS and it's less than 1% off. I don't really pay attention to the avg. mpg displayed on the computer but i know it reads low by one 1-2mpg the few times I have looked at it before resetting .

I'll often see an instant display of >65mpg while on the highway cruising at less than 70mph when I have a good tail wind or am catching a slight draft from a truck in front of me. I've actually seen >70mpg while >70mph when I have had a super strong tail wind.

Like I said though, I am -3 in the back and that made a small difference before/after changing the gearing.

It could make a difference, yes. Especially if you often ride longer distances.

I can see the 55mpg average given no ethanol gas, the different drive ratio, and a careful driver with a driving pattern that's good for mileage. I can't see the average going higher though.

Regarding the instant mileage, I have seen ridiculous numbers there, especially on trips like through Yosemite, where the average speed is 35 to 45 mph, and coming from Mono Lake going West it's only a short climb and than pretty much downhill or flat all the way home for me. But even there I never got better than 4L/100km for a full tank which is about 59mpg. And that's a not easy to repeat event as I somehow need to get to that "top of the hill" to roll back down again.

My 2012 Tiger 800XC has Touratech Zega Pro Side Cases and Top Case, so there's plenty of wind resistance. I also have a MadStad 22 inch adventure winshield as well. Running between 65-70 MPH my average miles per gallon ranges between 50-55 mpg. Out here in New Mexico we have lots of wind during the day and facing a headwind drops the MPG to between 45-50 MPG, and less.

I'm sure size of the rider will have an effect as well. I 'm 6 ft 3 and weigh 230 lbs.

I don't ride like a Hooligan ALL day, just here and there... The one day I rode it semi-hard all day I averaged something like 51-52 mpg. I hand calculated it two weeks ago on the way to Denver and back, 60mpg... So... yeah "Hooligan" likely is mellower for me than you, but I am tickled with the fuel mileage so far.

Everybody I've talked to with an aftermarket pipe and mapping gets poor mileage compared to stock, have you modified yours?

I average 45 mph in the city running the nuts off of it, and averaged 51 on my last trip. Yes, that's U.S. mpg. I have no doubt it I rode it with any level of sanity on a trip it could hit closer to mid 50's.

One thing to note is the mileage got considerably better once it really broke in, upwards of 6000 miles. Also not coincidentally I'm sure, the latest map is producing my best mileage yet.

This has been my experience too, however, I don't believe my dealer changed the map when it went in for turn signal replacement.

CUG, I stand corrected. I have hand checked it once, got 60+ but wasn't flogging it...

Interesting. I've seen that a few times that the computer was on something the person owning it wasn't expecting. Not that this is something new with computers, but it shows that a) set up from the dealers seems to be lacking and b) the computer isn't really obvious in what it's showing.
